Abstract: 307,828. Krupp Grusonwerk Akt.-Ges., F. March 14, 1928, [Convention date]. Addition to 265,153. Extrusion presses.-In a worm press in which a feeding worm 5 is carried by a sleeve 6 on the shaft 3 of the pressure worm 4, the sleeve and shaft being connected by a yielding clutch 7, 8, as described in the.parent Specification, a movable portion of the clutch is connected to apparatus for regulating the supply of material under treatment. As shown, the material is supplied from a heating fan 19 by blades 20 on a shaft 17, the blades pushing the material over an opening 22 in the base of a casing 21, so that it is delivered to the feed hopper 1<1> of the press. The shaft 17 carries a toothed wheel 28 engaged by a pawl 27 carried by an arm 26 connected by a rod 25 to a crank 24 on the stirring shaft of the heating fan 19. The clutch parts 7, 8 have corresponding depressions 12 and projections 11 with inclined edges which normally are in engagement under the pressure of a spring 13. If the conveyer worm 5 is choked, for example by excess feeding of the press, the clutch is disengaged and the part 8 moves axially, its motion being communicated by means of a lever 15 and rod 16<1> to a sector which is interposed between the pawl 27 and the wheel 28, and thus stops the feeding action of the blades 20.

Title: Tire cords and fabrics and tires including the same
Inventor: DRUMMOND FELSOM E
IPC: D06M15/03
Filed: 1958-02-24
Abstract: Tyre cords are impregnated with a stable aqueous dispersion or solution of dextran, which may contain an organic solvent and are then coated with rubber.  "Native" dextran obtained by inoculating a sucrose-bearing nutrient medium with a dextran-producing micro-organism, e.g. of the Leuconostoc mesenteroides or L. dextranicum types, or with the enzyme of the microorganisms, and having molecular structural repeating alpha-1,6 to non-alpha-1,6 linkage ratios in the range between 1.9 : 1 and 30 : 1, a molecular weight of 5,000-150 x 106, as determined by light scattering measurements, a solubility or dispersability in water such as to yield colloidally stable aqueous solutions or dispersions of 0.5%-50% by weight concentration and a colloidal osmotic pressure in liquids of 1-300 mm Hg, is preferably used.  Alternatively, lower molecular weight dextrans, i.e. having molecular weights of 5,000 or lower, obtained by hydrolising "native" dextran with acids or enzymes, may be used.  The aqueous solution or dispersion, which may contain 0.5%-35% by weight of an organic solvent, e.g. a water-miscible alcohol or ketone, an amide such as formamide or a dialkylated amide such as dimethyl formamide, preferably contains 0.5%-50% by weight of dextran.  The cards may be treated with the dextran dispersion or solution at round elevated temperature, dried, formed into a fabric, which is preferably weftless, and coated with rubber, or the cards may be formed into a fabric which is then impregnated with the dextran dispersion or solution and passed through a calendar in which rubber is applied to it.  Tyre cords made from cotton, regenerated cellulose, polyesters, polyamides and polycarboanhydrides of the type derived from alpha amino acids may be treated.

Title: Process for the production of sulphur hexafluoride
Inventor: HEINRICH LOTHAR
IPC: H01M4/96
Filed: 1966-02-10
Abstract: <PICT:1075525/C6-C7/1> Sulphur hexafluoride is made by electrolyzing hydrogen sulphide in anhydrous H.F., applying 7-20V and preferably 7-8V.  Current density of at least 0.023A cm2 is used, a nickel anode and an iron cathode spaced 2 to 5 mm.  H2S is admitted to the H.F. in a finely divided stream and at the rate of 0.094 to 0.1 g per ampere hour.  An electrolytic cell 1 has a number of anodes and cathodes arranged alternately and is cooled by brine. Hydrogen sulphide stored in a receiver 14 from a supply cylinder 13, passes in controlled amount governed by pressure into the cell containing H.F. and KF.  A reflux condenser retains H.F. in the cell, and the electrolytic product passes through a safety vessel 3 and frit 5 in water washing plant, two lye washers 7 and a sodium sulphite washer 8, where oxygen difluoride and other by-products are removed.  The treated gases are then dried by KOH tower 9 and CaCl2 tower 10.  Sulphur hexafluoride is condensed at a tower 11 cooled by liquid hydrogen. Electrolytically produced hydrogen escapes through a meter 12.

Title: Roller briquetting press for briquetting ores, coal or similar substances
IPC: B30B15/30
Filed: 1957-02-22
Abstract: 814,344. Roller briquetting presses. KLOCKNER-HUMBOLDT-DEUTZ A. G. Feb. 22, 1957 [Feb. 23, 1956], No. 6039/57. Class 87(2). A press for briquetting ores, coal &c. comprises a pair of rollers 17, 18 geared to rotate in opposite directions and a distributing box 35 with an aperture 43 above the pair of rollers, the distributing box being associated with a vibration generator which sets it in vibration primarily in the vertical direction. As shown in Fig. 4, the bottom 40 only of the distributing box is connected to the vibrator 51 and comprises a flat plate with a tapering rim 42 which surrounds the bottom of the box 35 and with a funnel 44 which opens into a shoot 45. Connection between the box 35 and rim 42 is through lugs on each with rubber shock absorbers interposed. The vibrator comprises electromagnets which, when energised by alternating current at 50 cycles per second, are attracted intermittently to an armature so that 6,000 vibrations per minute are produced ; if a rectifier is interposed, the vibrations are at 3,000 per minute. The vibrations may also be controlled by varying the frequency and, as regards their amplitude, by adding weights to the magnet. Vibrations of 1,000-1,500 per minute may be produced mechanically by unbalanced weights on oppositely rotating shafts, so arranged that the horizontal components balance each other but full effort is given to the vertical components. A vertical shaft 38 carries a double arm 39 which feeds the material. The width of the shoot 45 is the same as that of the rollers, Fig. 2, but one or more of its walls, e.g. 57, may be pressed inwards, e.g. by a rod 59 operated by a handwheel 60, so that the material, de-aired by the vibration, is pre-compressed on its way to the space 55 between the rollers. The rollers are formed to press e.g. egg-shaped briquettes and comprise robust wheel bodies with shrunk-on rims 63 of wear-resistant material. Rectangular bearing blocks 8, 9, 10 for the shafts of the rollers and gear wheels are held apart by spacer members and shims 31 are inserted to allow for compensation of wear on the roller surfaces, the whole being retained by a wedge 32 which may be constructed to protect against excessive shear forces.

Title: Improvements in and connected with impregnated paper

Abstract: 832,621. Resin-impregnated paper; battery separators. FAIRWEATHER, H. G. C. (Riegel Paper Corporation). Feb. 28, 1956, No. 6177/56. Class 96. In making permeable paper having a very large number of minute pores, cellulosic fibres having a maximum diameter of 20 microns, e.g. cotton linters, are made into an aqueous pulp in a hydropulper 1 and a refiner 2. The pulp is diluted with water and fed into the flow-box 20 of a Fourdrinier papermaking machine having a wire 12 travelling in a triangular path around a breast roll 13, a supporting roll 14 and a suction couch roll 15; a supporting roll 17 and a stretch roll 16 being provided along the lowermost run of the wire. The diluted pulp is fed on to the upwardlyinclined portion of the wire from an extension 21 of the flow-box to form a paper web. Some water is removed from the web by suctionboxes 18 and 19. The web is transferred by a roll 24 on to an endless travelling felt 4, on which it is pressed by small rolls 6, and passes on to a travelling endless wire or felt 25, which carries the wet web around a roll 28 and through an aqueous solution of phenol-formaldehyde resin, in the " A " stage of condensation, contained in a tank 7, and then around a roll 27. The resin-impregnated web is then transferred to an endless travelling wire 8. Excess resin solution is removed by suctionboxes 10 and the web is smoothed by a roll 32. The web is then passed around a drying cylinder 11 against which it is held by a felt or wire 33. The drying cylinder is heated to a temperature between 220‹ and 280‹ F. at which temperature the resin is cured to the " B " stage of condensation. The resulting dry resin-impregnated paper has a maximum ohmic resistance of 0.067 ohms per square inch, per thousandth of 46 an inch of thickness and contains between 20 and 65% of resin based on the total weight of resin and fibres. In making battery separators from the paper, it is cut into pieces which are compressed at their edges and then heated to a temperature of about 300 ‹ F. to cure the resin to the " C " stage of condensation.
